                                        java.lang.String inclusiveNamespaces)
                                 throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeSubTree in class CanonicalizerSpi

Parameters:

rootNode -

inclusiveNamespaces -

Returns:

none it always fails

Throws:

CanonicalizationException

engineCanonicalizeSubTree

public byte[] engineCanonicalizeSubTree(org.w3c.dom.Node rootNode,
                                        java.lang.String inclusiveNamespaces,
                                        boolean propagateDefaultNamespace)
                                 throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeSubTree in class CanonicalizerSpi

Parameters:

rootNode -

inclusiveNamespaces -

outputAttributesSubtree

protected void outputAttributesSubtree(org.w3c.dom.Element element,
                                       NameSpaceSymbTable ns,
                                       java.util.Map<java.lang.String,byte[]> cache)
                                throws CanonicalizationException,
                                       org.w3c.dom.DOMException,
                                       java.io.IOException

Output the Attr[]s for the given element.
The code of this method is a copy of outputAttributes(Element, NameSpaceSymbTable, Map), whereas it takes into account that subtree-c14n is -- well -- subtree-based. So if the element in question isRoot of c14n, it's parent is not in the node set, as well as all other ancestors.

Specified by:

outputAttributesSubtree in class CanonicalizerBase

Parameters:

element -

ns -

cache -

Throws:

CanonicalizationException

org.w3c.dom.DOMException

java.io.IOException

outputAttributes

protected void outputAttributes(org.w3c.dom.Element element,
                                NameSpaceSymbTable ns,
                                java.util.Map<java.lang.String,byte[]> cache)
                         throws CanonicalizationException,
                                org.w3c.dom.DOMException,
                                java.io.IOException

Output the Attr[]s for the given element.
IMPORTANT: This method expects to work on a modified DOM tree, i.e. a DOM which has been prepared using XMLUtils.circumventBug2650( org.w3c.dom.Document).

Specified by:

outputAttributes in class CanonicalizerBase

Parameters:

element -

ns -

cache -

Throws:

CanonicalizationException

org.w3c.dom.DOMException

java.io.IOException
